Flowers: Flowers are yellow, appearing July-August. A single flower
appears atop each stem. Each flower
has 15-30 yellow rays and brownish-yellow flowers in the central disc. The central disc contains
20-75 ray florets.

Fruits: Ray flowers fall off, leaving a central brown dome of sharp
projections. A single barely noticeable 4-sided achene, shaped like a pointed tooth and ¹/₁₆-⅛" (3-4 mm) long, is produced
in each flowerhead.
